G-Sync eliminates screen tearing by forcing a video display to adapt to the frame rate of the outputting device rather than the other way around as in traditional methods.
This eliminates the problem where a refresh could occur halfway through the process of a frame being output by the device, resulting in two frames being shown at once.
In this technology the VSYNC and HSYNC should be adaptive.
Does the Xilinx LogiCORE IP DisplayPort Support this Adaptive-Sync or G-Sync?
The Xilinx DisplayPort IP does not support Adaptive-Sync or G-Sync technology.
For information on the newer Xilinx DisplayPort IPs such as Xilinx DisplayPort 1.2 Subsystem, or Xilinx DisplayPort 1.4 subsystem, please see their master Answer Records. (Xilinx Answer 65447) (Xilinx Answer 70294)
